Effectiveness of exhaustive search and template matching against watermark desynchronization
Mauro Barni · IEEE Signal Processing Letters · 2005
By focusing on a simple example, we investigate the effectiveness of exhaustive watermark detection and resynchronization through template matching against watermark desynchronization. We find that if the size of the search space does not increase exponentially, both methods provide asymptotically good results. We also show that the exhaustive search approach outperforms template matching from the point of view of reliable detection.
